Engineered To Deliver A Long Lasting Seal In Tough Builds

The Cometic C5839-080 is a multi-layer steel head gasket specifically designed for the 1999-2003 7.3L Powerstroke engine, providing an ideal combination of strength, flexibility, and precision fitment. With a 4.140-inch valve-pocketed bore and .080-inch compressed thickness, this gasket is well-suited for engines running custom tolerances or undergoing rebuilds where thicker sealing is required. Its five-layer construction allows it to manage high combustion pressures while resisting the thermal expansion and contraction that can lead to gasket failure. Materials like galvanized steel, graphite, and armor-clad reinforcement provide excellent sealing across irregular or imperfect surfaces, especially in applications where cylinder heads or blocks have seen extensive use. The gasket is not side-specific, making installation more straightforward in tight engine bays. It’s an excellent fit for both stock and modified builds where consistency, strength, and long-term sealing are essential. Built to handle the harsh operating environment of diesel engines, this Cometic MLS gasket ensures your Powerstroke continues running strong mile after mile.
